New rack questions

When you had the probe on the flexwatt and the thermostat set above 100 how hot did the flexwatt get?

The helix said 100. I gotta be losing all the heat somehow

my guess is that back heated rack (which is very inefficient at transferring heat compared to belly heat racks) + cool room = tubs not getting hot enough.

If you can't get this figured out would it be possible to reconfigure the rack into a belly heat rack?

I just built a new rack because our old malamine one had back heat and to put it bluntly, it sucked balls (pun intended). We were having the same problem. Thermostat was set to 108 and the back of the tubs were barely getting to 90. Keep in mind that was only the back of the tub, not the ambiant temps. Belly heat keeps the hotspot more in the tub so the snake can place more of itself on the heat and since the flexwatt is closer to the tub there is way less heat loss. Therefor the ambiant temp in the tubs gets better as well. If its possible, I would order some flexwatt and rig our rack up to use belly heat and you will not regret it.

I'm going to pick up a piece of foam board tomorrow and see how that works. In my new house the rack will be in a walk in closet so should be nice and warm. My house now is insulated as good as a barn lol, which is the main reason I'm moving. $600 heat bills a month aren't fun

Also would mini blinds on the front hold heat too? Probably not too much

Not a noticeable amount

You could also get a oil filled space heater to heat the room.

I nailed a piece of linoleum on the back. It's working great. My helix is at 100 and warm spot is steady 91

I use 1/2 blue foam insulation on the sides and TOP and bottom of the rack. I test the snot out of everything and I found that adding to the top helped a fair bit more than the back alone. I would expect that is something you should plan on as well. I hear your power bill I used to heat the room and 1000$ a month was not reasonable. I have added 5 snakes since than and have the bill down to 100$ a month. In the long run the extra measures I took paid for them selves in a couple of months.
